Android-GraphQL-Apollo client – Query unresolved reference

I am trying to integrate graphql in my android project.My package name is app.android.mylife.
I have set
apollo { packageName.set("app.android.mylife") }
in my gradle file.

I created the same package structure for graphql folder also.
main-graphql-app-android-mylife->(here all graphql files)
I am having schema.json file which is also integrated .
And defined the query like this
test query.
When i execute this query with graphql plugin in android studio it gives response properly.
Then i rebuilt the project.
When i use the auto generated class BlogPostsQuery, it give unresolved refernce when compiled.
How can i solve it.
